American engineers have developed miniature sensors, through which a person can monitor the quality of air in real time using his smartphone. Scientists emphasize that these devices in particular will be useful for people suffering from chronic diseases, for example, bronchial asthma or allergy, in which the patient should avoid exposure to pollutants.
CitiSense - this is the name of this device, which is by far the only device capable of monitoring the quality of air in real time and displaying the results of verification on screens of smartphones and computers.
Many people believe that the pollution of the atmosphere occurs evenly and therefore the level of concentration of harmful gases in the air is the same. Odako is not so, the air is polluted non-uniformly, and in the area of busy highways, for example, the level of harmful gases will be much higher than in the distance from large roads.
Information about the state of the air is available not only to the owners of the device, but also to all who are interested in this. Apparatus that is equipped with sensors form a network that generates information about a certain territory.
The quality of the air breathed by a person - makes a huge contribution to his health, so you need to take this seriously. Probably most people do not think much about it because they do not have the opportunity to know how much air is polluted in the place where they are, so it's easier to assume that we breathe clean air rather than breathing a mixture of harmful gases.
Using CitiSense to find out how clean the air is, it's easier than ever - the EPA color scale displays a certain color, if you see a green one, then there is no threat, but the purple indicates that not everything is as good as it might seem.
Developers of this device, employees of the University of California, hope that with the help of CitiSense people will take care of their health more carefully and bypass those contaminated sites, which the sensor signals. In addition, this will be an additional motivation for residents of hazardous areas, so as not to turn a blind eye to the problem, and seek help from local authorities.
30 people, participants of the experiment, became the first who tried the new technology. They received prototypes of the CitiSense sensor and used them in everyday life for a month. It turned out that the most polluted zones are densely populated areas. It was also found that those people who make their own contribution to the elimination of air pollution, unfortunately, suffer the most. The most dangerous were cyclists and people who were waiting at the stop for public transport. But drivers of cars, on the contrary, though they produce exhaust fumes, suffer from their impact much less.
At the moment, CitiSense is a rather weighty device and can not be built into smartphones, but soon the integration of sensors will be possible, and with mass production, the price for them will be acceptable for everyone.
